Wiznet5100 ethernet shield on nRF52840

[ToasTer86]

Dear Nordic Devzone,

I want to run an Arduino Ethernet Shield with the Wiznet5100 on the nRF52840. I was wondering if there was an easier way to do this then having to rewrite the SPI code by myself.

www.arduino.cc/.../ArduinoEthernetShieldV1

Currently I am using the Keil IAR /uVision to compile my code and can easily compile and run all the examples included. I am just a bit lost on how to use the ethernet shield with the nRF52840.

I thought I would be able to use some Arduino library to easily get it working.

Any help or direction in which to start would be much appreciated.

Hi,

You can find a nRF5x SPI library for the WIZnet 5500 chip at this github page. This should be a good starting point.

Also see this blog post about WIZnet's BLE to TCP Gateway.

Hi Sigurd, thanks again.

Yep I just figured that out before you messaged, I am sorry. Right now I am using this as well as a kind of logbook for what I have done.

So now it is still printing out

=== W5100 NET CONF ===
MAC: FF:FF:FF:FF:FF:FF
SIP: 255.255.255.255
GAR: 255.255.255.255
SUB: 255.255.255.255
DNS: 8.8.8.8
======================

in the network_init(); function on user_ethernet.c line 81 the gWIZNETINFO variable is filled before setting the ctlnetwork(CN_SET_NETINFO, (void*)&gWIZNETINFO); function. But after the set & get ctlnetwork(CN_GET_NETINFO, (void*)&gWIZNETINFO); gWIZNETINFO is empty again.

So will trouble shoot that now.

Really seems like I am getting somewhere at least. Thanks again Sigurd for all your help up till now.
